We look at the division of 260673 by 45 
The aim is to understand the frequency of 45 in 260673.

Advancing to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 45

Going ahead to step 2:
The number 45 fits into 26 0 times, leaving a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 45

Let's proceed to step 3:
The number 45 fits into 260 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 35 after subtracting 225 from 260.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 45

Going ahead to step 4:
The number 45 fits into 356 7 times, leaving a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we subtract 315 from 356, we get 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 45

Moving on to step 5:
45 can be fit into 417 9 times, resulting in a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 579.0
If we take 405 away from 417, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 45

On to step 6:
45 can be fit into 123 2 times, resulting in a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 5792.0
Deduct 90 from 123 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
45 can be fit into 330 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 5792.7
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 5792.73
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 5792.733
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 5792.733, and the remainder is 0.0015.
